230V 3 Phase Motor on 240V Single Phase Supply Answered

I am a ME with very limited knowledge on electrical side of the world.
I have ordered a electric motor from Germany with 240 V assuming it will be single phase.
The motor has rocked up with 230 V winding but 3phase connections.

Is there any chance I can connect this motor to our single phase supply??? 
Any device which will help to use this motor.
Please help.

Just to see what all those connections mean.

Do note, that because of the inaccessible internal connection you cannot use a Delta motor winding.


Where do you live?

10 volts is nothing service can vary by 20 volts.

Some 3 phase motors have 2 wire and 3 wire connection diagrams ether on the maker plate or under the connection box plate.

Open the connection box and see if it has 3, 6, 9, or 12 wires.

3 wires is fixed forward.

6 and up wires is reversible and may be able to convert from a 3 phase line to a 2 phase line depending on where you live.

A friend wound a single phase machine that can best be defined as a phase adder.

Normally the military uses MG (motor=generator) sets.

The phase adder has extra internal winding's which add the two more time displaced phases that let you power your 3-phase motor at the exact frequency.

you will however lose some power.
